Audio Visual Design Guidelines

Design and construction method including applied acoustic treatments

For the most common space types, it is desirable to employ a range of standard construction approaches to achieve the desired acoustic performance.

Typical advice formulated by the acoustic consultant might include:

Walls 

  • Stud size and spacing
  • Thickness/density of plasterboard
  • Internal acoustic treatments

Façade/windows

  • Glazing systems
  • Extent of glass vs solid walls

Ceilings

  • Type of ceiling (mineral tile, set plasterboard, perforated ply etc)
  • Appropriate treatment of slab in open/semi-open ceilings
  • Additional materials under roofs or plant floors

A standardised approach at any organisation helps control both capital and maintenance costs, but this must be evaluated against the unique character of each new construction project.

More complex issues or spaces will usually require multiple discrete approaches to the physical acoustics; in addition to the typical construction approaches above, including treatments such as:

  • acoustic treatments to limit noise from hydraulic or mechanical systems or other troublesome sources
  • diffusers, traps or other applied elements to control troublesome frequencies/bands
  • additional internal acoustic treatments to address problematic reflections
  • variable acoustics may be required for performance spaces to allow the room to change character to suit different types of performance
